Contraction Stress Test

A

Evaluates fetal oxygenation and ability to tolerate contractions w/o placental insufficiency

negative contraction test is desired
positive indicates late DHR decelerations

44
Q

Rh Incompatibility

A

AKA isoimmunization

When mom is Rh- and baby is Rh+, it has inherited this gene from the Dad, mom will create antibodies against the fetus, typically the first pregnancy is not affected, but antibodies grow with future pregnancies

If not treated, then fetus can become anemic or jaundiced with immature RBC production

No impact if mom is + and baby is -

Complication: Hydrops Fetalis

45
Q

Hydrops Fetalis

A

Untreated Rh incompatibility

Risk for anemia, cardiac decompensation, cardiomegaly or hapatospleomegaly

Hypoxia occurs due to severe anemia
Ascites occurs due to fluid mobilization and fluid develops in periotoneal cavity

46
Q

How do we test for Rh incompatibility?

A

Indirect Coombs - detects antibodies in Mom against Rh - fetus

Direct Coombs - detects antibodies against Rh+, performed with PUBS
